DEMENTIA signs and symptoms include memory loss, confusion and putting things in unusual places, such as placing an iron in the fridge. Treatment recommended to prevent dementia has included exercise, a healthy diet and not smoking. Now, a study has suggested that exercise may not help.

There’s evidence for a number of processes, from potentially transient changes in gene expression, through long-term changes in DNA packaging, and up to alterations of the connections among cells. Complicating matters further, none […]
Enlarge (credit: Katja Schulz) A number of bacteria that infect insects have a simple and brutal way of increasing their transmission: they kill off all the male progeny of the females that they infect. There’s actually some evolutionary logic to this. The bacteria can get transmitted to the eggs of the females they infect but […]

A number of Android phones have a tendency to skip the occasional security patch while making it appear that the device is fully up to date, Wired reports. Researchers with Security Research Labs (SRL) looked into 1,200 phones from manufacturers like Google, Samsung, Sony, Nokia, Huawei, Motorola, LG, HTC, ZTE and TCL and found that […]
We all know that AI can be used to swap faces in photos and videos. People have, of course, taken advantage of this tool for some disturbing uses, including face-swapping people into pornographic videos — the ultimate revenge porn. But if AI can be used to face swap, can’t it also be used to detect […]
There are side-effects associated with consulting the internet about health issues, including increased anxiety and a loss of privacy.
MIT researchers released a new tool called Squadbox that aims to combat online harassment. The tool allows users to let a group of friends, or “squad,” filter out harassing emails. Squadbox is only available for email right now, but it could soon expand to other private messaging systems, such as Direct Messages on Twitter or […]
(Reuters) — Over 50 top Artificial Intelligence researchers on Wednesday announced a boycott of KAIST, South Korea’s top university, after it opened what they called an AI weapons lab with one of South Korea’s largest companies. The researchers, based in 30 countries, said they would refrain from visiting KAIST, hosting visitors from the univ…Read More
These photos show dendrites after pulses of different current densities are applied, from lowest density at the top to highest at the bottom. Dendrites—branching structures that look like tree limbs—are fun to draw, good on neurons, but generally to be avoided in lithium-ion batteries. As ions are exchanged between the anode and cathode over several […]
